A covert cop becomes a target when she picks the wrong cover story The Treadwater Estate has become the epicentre of a series of strange events. People go missing. Bodies are found - buried and wrapped in clingfilm. Yet there appears to be no connection between the victims and no motive for the crimes. The estate looks anonymous, its residents inscrutable. Door-to-door inquiries fall flat. No one has seen anything, everyone resents the police presence. Someone must be hiding in plain sight. Faced with a wall of silence, to dig deeper DI Tara Grogan must get closer to the action than is safe. Not being from the area, a local choir provides her with an entry point. But will the very guise that she adopts to be accepted into the community, that of a reformed con, be her undoing? If her cover is blown, her life is in danger. But if she doesn't push her luck to the limits, a killer will get away with it.
